Imperativ

The imperativ singular form is usually the same as the first person singular form:
I kimm →   Kimm! (come!)
I beam →   Beam! (beam!)

1.pers plural: we

The 1.person plural verb form is usually build with -mma. (There is actually another form, too. But this is not relevant for now.)

mia samma = we are	mia beamma = we beam sb.
mia kemma = we come (sgl. i kimm)	mia kenma = we know sth.

(i kenn → mia kenma; of course you could write "kenmma" but n+m+m would be kind of an overkill, therefor you can drop a "m")

"ois klar" is literally: everything ok. But it can also mean to have understod something (as in "Aye aye Sir").
